Something being "real easy to test" does not make the test accurate or significant.
In your discussion, you're talking about volume. However, the relevant topics are not volume, but density and mass. Objects 'float' when they displace an amount of the fluid (water) with a mass equal to their own. In other words, a 100 ton iceberg floats when it raises the water level by whatever volume 100 tons of water is.
So, the iceberg in a solid state will raise the water level by 100 tons of water (divided by the area of the pool and all that). When you melt the iceberg, you have 100 extra tons of water... so an equal rise.
It should be noted that this is primarily applicable on the north pole, where the ice is actually floating. Antarctica, being an actual land mass, has ice that is not currently displacing sufficient water to float.
